Application filed. August 26, 1912. Serial No. 717,160.

To all whom it may concern:

Be it known that I, IRA H. GILLILAND, a citizen of the United States,residing at Erie, in the county of Erie and State of Pennsylvania, haveinvented certain new and useful Improvements in Detachable Calks forHorseshoes, of which the following is a specification.

My invention relates to horse shoes and has for one of its objects theprovision of means for detachably securing calks to the toe and heels ofthe horse shoe.

Another object of my invention is the pro vision of an improved horseshoe having detachable toe and heel calks, the calks on the two heelportions being oppositely disposed relative to one another.

My invention will be described in detail hereinafter and illustrated inthe accompanying drawings, in which- Figure 1 is a bottom plan view ofmy improved horse shoe showing the calks in position; Fig. 2, an endview from the heel portion of the shoe showing the calks removed; Fig.3, a perspective view of the toe calk;

Fig. 4, a view in perspective of the heel calk on the outside of theanimals hoof; Fig. 5, a view in perspective of the heel calk used on theheel portion of the shoe at the inside of the hoof; and, Fig. 6, afragmental view in perspective of the under side of the shoe at the heelportion to which the call: shown in Fig. 4: is attached.

In the drawings similar reference characters will be used to designatecorresponding parts throughout the several views.

1 indicates a horse shoe of the ordinary construction having aprojection 2 formed integral therewith and extending downwardly from theunder side thereof transversely of the toe of the shoe and otherprojections 3 and 4t extending downwardly from the under side adjacentto the heel portions of the shoe, said portions being provided withopenings 2 3 and 4?, respectively.

5 indicates a boss or projection extending inwardly of the shoe from thetoe portion thereof and 6 indicates another boss or proj eetionextending inwardly of the shoe adj acent to the heel portion of the armthat is adapted to be secured to the outer side of the horses hoof.

My improved toe calk consists of a bar 7 having it upper portion beveledto an edge as shown at 8 and provided with a forwardly extendingintegral lug or projection 9 that is adapted to engage the opening? inthe projection 2, and a rearwardly extending boss or projection 10 thatis adapted to seat upon the boss 5 heretofore described, and to besecured to said boss by means of a bolt or other suitable fastening 11inserted through an opening 12 in the boss 10 and a corresponding andalined opening (not shown) in the boss 5.

The calk that is adapted to be secured to the heel portion of the shoeon the outside of the animals hoof consists of a bar 13 beveled as shownat 14 to a sharp edge having a vertical wall 15 toward the outside ofthe shoe, said bar being provided with a tongue or projection 16extending fro-m its rearmost end and adapted to engage the opening 3 inthe projection 3. Said bar 13 is also formed with an integral boss orprojection 17 that is adapted to seat upon the boss 6 and to be securedthereto by means of a bolt or similar fastening member 18 engaging anopening 19 in said boss 17, and a similar opening (not shown) in theboss 6. The bar 13 is also provided with a downwardly extending tongueor projection 20 from the vertical wall 15 at the forward terminal ofsaid bar 13, said tongue or projection being formed with an inwardlyextending terminal 21, said tongue 20 and its terminal 21 constituting ahook member that is adapted to seat within a recess 22 in the side ofthe shoe and a recess 23 in the bottom thereof, said recesses 22 and 23being continuous.

The calk that is adapted to be secured to the heel portion of the shoeon the inner side of the animals hoof comprises a bar at that is beveledas shown at 25 to a sharp edge and has an integral tongue or projection26 that is adapted to engage the opening P in the project-ion 4. and anoppositely extending boss or projection 27 that is adapted to be securedto the shoe by means of a bolt 28 or other similar fastening engaging anopening 29 in said boss or projection 27 and a similar and alinedopening (not shown) in the shoe.

It will be understood from an inspection of the drawings and the abovedescription that any or all of the calks are adapted to be displaced torenew the same when broken or worn out and that the specific means forsecuring the calks in position not only contribute to this end but alsoprovide means to securely hold the calks on the shoe. Furthermore, byhaving the calks on the heel portion of the shoe secured to the outerside of the hoof with the edge formed by the beveled portion 14extending substantially longitudinally of the arm of the shoe and withthe vertical face 15 toward the outer side of the hoof and shoe the shoeis especially adapted to prevent the animal from slipping sidewise whilein motion. The hook shaped member consisting of the flange 20 and itsterminal 21 engaging the shoe contributes to securely hold the calk onthe heel of the shoe and to brace it while in position to prevent theslipping thereof from position.

Having thus described my invention what I claim is 1. The combinationwith a horse shoe having an integrally formed downwardly proj ectingperforate lug arranged adjacent one heel terminal, of a heel calkincluding a beveled body member, a laterally extending securing platecarried thereby and formed flush with the shoe engaging face of saidbody member, said plate being adapted to be secured to an inwardlyextending laterally disposed lug formed integrally with said shoe, meansfor detachably securing said plate to said inwardly extending laterallydisposed lug, a tenon projecting laterally from said calk and seated inthe assembled position of the call: in the said perforation of saidperforate lug, and an integral L-shaped locking tongue formed on saidcalk and adapted to be seated in a corresponding mortise formed in saidshoe.

2. The combination with a horse shoe having a mortised vertical lug anda perforate lateral lug formed adjacent one heel terminal, of a heelcalk including a beveled body member, a lateral tenon formed on saidbody member, a securing plate carried by said body member, means forsecuring said plate to said lateral lug, and an L- shaped locking tongueformed integrally with said body member and adapted to be seated in areceiving mortise formed in said shoe.

3. The combination with a horse shoe of an integral downwardly extendingmortised lug, and a lateral inwardly extending lug, said lugs beingformed integrally with one heel terminal of said shoe, and a heel calkincluding a beveled body member, a securing plate formed on said bodymember, means for attaching said plate to said lateral lug, a tenonformed on said body member, and seated in the assembled position of thecalk in the said mortise of the downwardly extending lug, and anintegral L-shaped looking tongue formed on said member and adapted to beseated in a receiving mortise formed in said shoe.

In testimony whereof I afiix my signature in presence of two witnesses.

IRA H. GILLILAND.
